4 Students will understand and apply scientific concepts, principles, and theories pertaining to the physical setting and living environment and recognize the historical development of ideas in science.
1 Living things are both similar to and different from each other and from nonliving things.
1.1 Describe the characteristics of and variations between living and nonliving things.
1.1a Animals need air, water, and food in order to live and thrive.
the characteristics of some animals change as seasonal conditions change (e.g. , fur grows and is shed to help regulate body heat; body fat is a form of stored energy and it changes as the seasons change)
3.1b Each plant has different structures that serve different functions in growth, survival, and reproduction.
roots help support the plant and take in water and nutrients
4.1e Each generation of animals goes through changes in form from young to adult. This completed sequence of changes in form is called a life cycle. Some insects change from egg to larva to pupa to adult.
5.2 Describe some survival behaviors of common living specimens.
5.2a Plants respond to changes in their environment. For example, the leaves of some green plants change position as the direction of light changes; the parts of some plants undergo seasonal changes that enable the plant to grow; seeds germinate, and leaves form and grow.
5.2b Animals respond to change in their environment, (e.g. , perspiration, heart rate, breathing rate, eye blinking, shivering, and salivating).
6.1d Decomposers are living things that play a vital role in recycling nutrients.
6.1e An organism s pattern of behavior is related to the nature of that organism s environment, including the kinds and numbers of other organisms present, the availability of food and other resources, and the physical characteristics of the environment.
6.2c Heat energy from the Sun powers the water cycle (see Physical Science Key Idea 2).
7 Human decisions and activities have had a profound impact on the physical and living environments.
7.1 Identify ways in which humans have changed their environment and the effects of those changes.
7.1a Humans depend on their natural and constructed environments.
7.1b Over time humans have changed their environment by cultivating crops and raising animals, creating shelter, using energy, manufacturing goods, developing means of transportation, changing populations, and carrying out other activities.
7.1c Humans, as individuals or communities, change environments in ways that can be either helpful or harmful for themselves and other organisms.
